97663-73-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 97663-73-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,6,6 and 3 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 97663-73:
(7*9)+(6*7)+(5*6)+(4*6)+(3*3)+(2*7)+(1*3)=185
185 % 10 = 5
So 97663-73-5 is a valid CAS Registry Number.

4,5-DIPHENYLIMIDAZOLES FROM THE CYCLIZATION OF BENZIL N-ALKYLMONOHYDRAZONES
Collibee, William L.,Anselme, Jean-Pierre
, p. 655 - 662 (2007/10/02)
The thermal cyclization of monodisubstituted hydrazones (1) affords the corresponding N-substituted-4,5-diphenylimidazoles in good to excellent yields; possible mechanisms for this unusual cyclization are presented.
